Which symptom may accompany hypoglycemia?

• A. Fruity breath
• B. Rash
• C. Clammy skin
• D. Nausea

Answer: (C)

Clammy skin is a classic sign of hypoglycemia because low blood glucose stimulates the autonomic nervous system to release adrenaline, which brings on sweating and a pale, cool, clammy skin appearance. This combination—sweating with pale, moist skin—is a common clue that glucose is slipping too low.

Fruity breath points to high glucose with ketosis, such as in diabetic ketoacidosis, not low blood sugar. Rash isn’t a typical feature of hypoglycemia, and while nausea can occur with various conditions, it isn’t as characteristic for hypoglycemia as the sweating and clamminess. Other common signs you’d look for include shakiness, hunger, and confusion.
